Add a report to NotebookLM and generate an expandable map of its topics and related material to help choose what to read closely.
Execution environment and usage
AI / software
NotebookLM / Gemini Notebook
Where to operate
Mind Map in Google’s notebook web interface; current help pages use the name Gemini Notebook.
Getting started
- Open notebook.google.com in a browser, create a notebook and add source documents.
- Generate a Mind Map, select a branch, then ask follow-up questions in chat.
Setup and plan requirements
A Google account with service access and authorized source material; verify successful import first.
Prompt portability limits
Reuse questions elsewhere only after supplying sources again. Citations, audio and mind-map features do not transfer with text.
Usage limitations
As of 2026-10-20, the official standalone web service country list includes Taiwan but does not list Hong Kong or Macau. This does not establish App or API availability. Account and feature restrictions still need checking; local access has not been tested.

適用情境 / When to use
For a report too long to know where to start: add the successfully imported report to NotebookLM and generate an expandable topic map. Select a branch, ask follow-up questions and check citations. It guides reading rather than replacing the report; a drawn connection does not establish causation.
步驟 / Steps
- Add sources about the same topic to a notebook.
- Generate a Mind Map and explore its topic branches.
- Select a branch, then use the prompt below in chat to ask follow-up questions and check citations.
提示詞 / Prompt
For [branch name] in this mind map, identify the core concepts needed before reading. Explain them using the selected sources with citations, and flag insufficient source support. Explain whether its relationship with [other branch] is explicitly supported. Do not treat a conceptual connection as causation.
留意事項 / Cautions
- A connection between concepts does not necessarily imply causation.
- Feature names, devices and interfaces may change between versions.
